The image is showing two possible ways non-homologous chromosomes may line up during metaphase 1 of meiosis 1. Which of Mendel's laws is this image depicting?
Answer:
The correct answer is Mendel's Law of Independent Assortment.
Final answer:
The image depicting non-homologous chromosomes lining up during metaphase I of meiosis I demonstrates Mendel's Law of Independent Assortment. This law explains that alleles of different genes are distributed to gametes independently.
Explanation:
The image depicts non-homologous chromosomes lining up during metaphase I of meiosis I, demonstrating Mendel's Second Law, the Law of Independent Assortment. According to this law, alleles for different traits are distributed to gametes independently of one another.
This is illustrated during metaphase I when chromosomes align at the metaphase plate in random orientations; this means that the orientation of one pair of homologous chromosomes does not affect the orientation of another pair. Consequently, the resulting gametes can possess any combination of the paternal and maternal alleles. It is important to note that this law holds only for non-homologous chromosomes, as genes located on the same chromosome may demonstrate linkage and do not assort independently.

What is key to preventing extinction of any one species?
"The energy necessary to perform this function comes directly from the
(1)exchange of H2O and O2 during respiration
(2)blood flowing through the organs
(3)ATP molecules produced during cellular respiration
(4)water that is eliminated by the organs"
The energy needed for biological functions comes from ATP molecules produced during cellular respiration (Option 3), involving the digestive, cardiovascular, and respiratory systems.
Explanation:The energy necessary to perform functions in living organisms mainly comes from ATP (adenosine triphosphate) molecules produced during cellular respiration (Option 3). Cellular respiration is an intracellular process that converts glucose and oxygen into carbon dioxide, water, and most importantly, ATP. This process requires the involvement of the digestive, cardiovascular, and respiratory systems. Digestion breaks down food to obtain glucose, while the respiratory system facilitates the exchange of gases, providing oxygen to the body and expelling carbon dioxide. ATP then is used as the main energy source for various biological processes.

Respiratory structures in order of airflow from outside to inside the body
Final answer:
Air journey from the external environment to the alveolar sacs involves several structures, starting with the nasal cavity and moving through the pharynx, larynx, trachea, primary bronchi, secondary and tertiary bronchi, bronchioles, and onto the alveolar ducts and sacs where gas exchange occurs.
Explanation:
The journey of air from the outside to the inside of the body involves passing through several structures that are part of the respiratory system. Understanding this pathway can provide insights into how our bodies process air for the essential exchange of oxygen and carbon dioxide, which is vital for cellular respiration and energy production.
Nasal cavity: The first point of entry where air is warmed, humidified, and filtered.Pharynx: This serves as a path for air from the nasal cavity to the larynx.Larynx: Often referred to as the voice box, it directs air into the trachea and prevents food from entering the airway.Trachea: This tube, also known as the windpipe, further conducts air to the bronchi.Primary bronchi: The trachea splits into the left and right bronchi, each leading to a lung.Secondary and tertiary bronchi: These are further divisions within the lungs, branching into smaller passages.Bronchioles: Smaller tubes that distribute air to different regions of the lungs.Terminal and respiratory bronchioles: Final branches that lead air into the gas exchange sites.Alveolar ducts then alveolar sacs: Structures where gas exchange with capillaries occurs, allowing oxygen to enter the blood and carbon dioxide to be expelled.Each of these structures plays a critical role in ensuring air is properly processed for gas exchange, demonstrating the complexity and efficiency of the human respiratory system.

mis of white and red hairs. This blend of colors is called roan. What can you infer about the pattern
of inheritance involved in the formation of a roan coat in cattle? Explain your answer.
Answer:
When homozygous white cattle are crossed with homozygous red cattle, each of the offspring has a mix of white and red hairs. This blend of colors is called roan. What can you infer about the pattern of inheritance involved in the formation of a roan coat in cattle?
WW x RR= WR, WR, WR and WR
WW= Homozygous white cattle
RR= Homozygous red cattle
WR= Roan (Mix of red and white cattle)
WR x WR= WW, WR, WR and RR
When the roan cattle (WR) is crossed with one another, the offspring produced gives a mix of white and red cattle (75%) and homozygous red cattle (25%).
Explanation:
If when homo-zygous white cattle are crossed with homo-zygous red cattle, offspring have a mix of white and red hairs, then it is a case of codominance.
Diploid organisms (such as cattle) inherit two gene forms or 'alleles' for a given gene locus, one from each parent.An individual is homo-zygous when inherits the same alleles for a given gene locus, whereas an individual is heterozygous when inherits different alleles for a given gene locus.In cases of codominance, both alleles are expressed in heterozygous individuals, thereby forming a phenotype that is different from parental phenotypes in a double homo-zygous cross.In conclusion, if when homo-zygous white cattle are crossed with homo-zygous red cattle, offspring have a mix of white and red hairs, then it is a case of codominance.

Final answer:
The bionic pancreas assists in maintaining homeostasis by regulating blood sugar levels to normal through the administration of insulin, but it does not cure diabetes.
Explanation:
According to the passage, the bionic pancreas makes corrective actions that return blood sugar levels back to normal. This artificial device helps maintain homeostasis by adjusting the amount of insulin in response to the blood glucose levels, similar to how natural pancreatic function maintains blood sugar levels through the secretion of insulin and glucagon. This bionic device works to regulate blood sugar levels, but it does not cure diabetes, produce more sugar, or break down blood cells.

Common name and scientific name of disease and organism that causes the disease
Some history about the disease like when were the worst/most recent outbreaks, what were some older types of treatments and remedies, how did people think the disease was transmitted, what did people do to avoid it and more
How the disease is transmitted
How the disease affects humans including symptoms
How the disease is treated today
Any other interesting facts you find
Include a works cited page with at least 4 different sources (2 for each disease)
Answer No 1:
Bacterial Disease:
Common name : Typhoid
Scientific Name: Typhi
History About disease:
Typhoid can be described as an acute illness which is caused by the bacteria: Salmonella enterica serotype Typhi.
Typhoid fever was responsible for a widespread plague in Athens in 430BC. This outbreak proved to be fatal for one third of the population of Athens. It is difficult to determine the cause of plagues and infectious diseases in early history, although some speculation is usually allowed.
Jamestown, an English colony in Virginia, is also thought by some historians to have died out as a result of typhoid fever. The fever proved fatal for more than 6000 settlers between 1607 and 1624, and may have been responsible for eliminating the entire colony.
Military and war environments have often been subjected to the presence of typhoid fever throughout history. In excess of 80,000 soldiers died as a result of typhoid fever or dysentery in the American Civil War. Likewise, the Spanish-American War led to infections with typhoid both on the field and in training camps.
Answer No 2:
The bacteria that cause typhoid fever spread through contaminated food or water and occasionally through direct contact with someone who is infected.The majority of people in industrialized countries pick up typhoid bacteria while traveling and spread it to others through the fecal-oral route.
This means that Salmonella typhi is passed in the feces and sometimes in the urine of infected people. You can contract the infection if you eat food handled by someone with typhoid fever who hasn't washed carefully after using the toilet. You can also become infected by drinking water contaminated with the bacteria.
Typhoid vaccine is used for the eradication of typhoid.
Answer No 3:
Name: Ebola
Scientific name: Zaire ebolavirus
Ebola is thought to first occur in Sudan in 1976. Ir infected over 248 people. the second Ebola virus emerged from Yambuku, Zaire, Ebola-Zaire (EBOZ).The third strain of Ebola, Ebola Reston (EBOR), was first identified in 1989 when infected monkeys were imported into Reston, Virginia, from Mindanao in the Philippines. Since then, the virus has been infecting people from time to time, leading to outbreaks in several African countries.
Answer No 4:
Ebola isn’t as contagious as more common viruses like colds, influenza, or measles. It spreads to people by contact with the skin or bodily fluids of an infected animal, like a monkey, chimp, or fruit bat. Then it moves from person to person the same way. Those who care for a sick person or bury someone who has died from the disease often get it.
Other ways to get Ebola include touching contaminated needles or surfaces.
You can’t get Ebola from air, water, or food. A person who has Ebola but has no symptoms can’t spread the disease, either.

Which statement accurately describes how magnetic stripes in ocean rock provide evidence of seafloor spreading?
The pattern of magnetic stripes shows that Earth's magnetic north has always been the same.
The presence of iron indicates that new material cannot be formed at mid-ocean ridges
The pattern of magnetic stripes shows that the seafloor is expanding at mid-ocean ridges
Answer:C.
Explanation:
Don’t know
Magnetic stripes in the ocean rocks provide evidence of seafloor spreading by the pattern of magnetic stripes shows that the seafloor is expanding at mid-ocean ridges. Thus, the correct option is C.
What are Ocean rocks?The oceanic crust or rock is primarily composed of rocks which are rich in iron and magnesium minerals. The rocks of the ocean floor contains iron. As the molten material cooled and harden, the iron bits inside these rocks lined up in the direction of Earth's magnetic poles, creating a pattern of magnetized stripes.
When the Earth's magnetic field reverses, a new stripe, with the new polarity forms. Such magnetic patterns lead to the recognition of occurrence of the sea-floor spreading, and thus remain as one of the strongest evidence for the theory of plate tectonics.
Therefore, the correct option is C.

By cross checking, the options given it is concluded that the traits for white fur and red eyes are not always inherited together, the two traits are governed by different genes and are independently exhibited in the individual as stated in law of independent Assortment.
If the traits for white fur and red eyes were always inherited together, it would contradict the hypothesis of independent assortment of alleles. Therefore, option (B) is correct.
The notion of independent assortment states that gamete production segregates alleles for distinct qualities. A continuous pattern of allele inheritance shows genetic linkage, which contradicts independent assortment.
In genetic linkage, genes close together on a chromosome are inherited together more often. If white fur and red eyes were routinely inherited together, they would be physically near on the same chromosome and more likely to be transferred together during meiosis. This contradicts independent assortment, which believes that homologous chromosomes randomly position during meiosis to segregate alleles separately.
In essence, if qualities that are not physically connected in the same chromosome are inherited together, it demonstrates departures from independent assortment and supports genetic linkage or interaction between those genes. Therefore, option (B) is correct.

Oops! You were cleaning out the aquarium in the biology lab and you accidentally placed the salt water fish in the freshwater tank. What will happen to the cells of these fish
Saltwater fish in freshwater and freshwater fish in saltwater both suffer from osmosis effects that can be fatal. Saltwater fish cells could swell and burst in freshwater, while freshwater fish cells could dehydrate and collapse in saltwater, due to differences in osmotic pressures.
Fish cells have semi-permeable membranes, allowing certain substances to pass through while blocking others. When a saltwater fish is placed into a freshwater environment, a process known as osmosis occurs, where freshwater flows into the cells of the fish, making the cells swell and potentially causing the fish to die.
Conversely, a freshwater fish placed in the ocean, which has a hypertonic environment in comparison to the freshwater fish's body fluids, will experience the opposite effect. Water from the fish's cells will flow out into the surrounding salty water, leading to cell dehydration and possible death. Both types of fish spend energy to maintain osmotic homeostasis; freshwater fish actively absorb salt through their gills and secrete dilute urine, while saltwater fish secrete salt through their gills and produce highly concentrated urine to manage the osmotic pressures.
